Products that do what EmailUSD – a new way to send and receive TRON USDT using email address does
Hi All! I wanted to show you guys EmailUSD, an app I’ve been working on for some time. It lets you send and receive TRON USDT using just email addresses simplifying onboarding and making it super easy to use + send and receive. I think for a lot of non crypto folks crypto is this scary new thing because the onboarding and usage experience is really novel. Upon introduction you have to write down your 12 words and we put scary messages everywhere about it. And then when you want to send and receive you have to transmit this complex combination of numbers and letters to someone and get it…

It's time for a better Venmo/PayPal... One that is globally accessible, makes you money and takes a cut of the profit instead of screwing you with fees and bad conversion rates I made the iOS + web app and I'm handing it to you Send USDC via email Btwn Friends is an open-sourced PayPal/Venmo alternative that let's you send stablecoins to anyone's email without them being on the app, having a wallet or knowing about crypto. Here's how it works Every P2P payment app makes you create an account, save 12 words, link to a wallet app, KYC, transfer gas tokens... It's intimidating and too…

Hey HN, I just released Tradofire, a crypto trading app I built using a lot of cursor chatgpt and claude for over a year. The main idea of the app is very simple - to swipe on pre-prepared trading setups (like tinder) and if you right swipe it opens a position. The execution of this simple idea was much more complex and tbh I could not have done it without AI. Here's a quick rundown of the main features: Swipe-to-Trade UI: Quickly initiate long or short positions with intuitive swipe gestures. Real-Time Trade Signals: Get curated crypto signals from the market delivered proactively, helping…

A friend(@wolever) and I spent the weekend hacking up a small web app which makes it easy for you to sell digital goods for Bitcoins. Once a customer has clicked the “buy” button, we take care of giving them a unique address, monitoring that address for transactions, then securely notifying your website once a minimum number of confirmations have been received. Oh, ya, and then we send you the Bitcoins :) The website is here: BitWillet: http://www.bitwillet.com and there is a demo on the front page. (full disclosure: BitWillet uses the Willet, http://dev.getwillet.com, platform, of which I…

Hi guys, I've written the first proof-of-mistake crypto token on top of Ethereum. You can see it at http://www.lostethereum.com/ It's basically a proof-of-burn substitute for users who mistakenly sent to the wrong address. It requires a web3 enabled browser, i.e chome with MetaMask, Parity, Mist, etc. This let's the web interface seamlessly interact with the Ethereum network. Let me know what you guys think.

Hey HN, I'm a longtime reader and this is my first Show HN (exciting!) It's a collaboration between me and two friends, and we're building this upon another app we made called EmailYak, an API to receive email. We're trying something new and releasing the documentation to an app while we're still building it. We'd love feedback. Do you belong to any of these categories? 1) You've built an app with two distinct groups of users (say, people with cars and those looking for a ride) and they were able to communicate with each other. Did you expose personal email addresses? Did you send…

I built this site to make it really easy to put cryptocurrency in the hands of people who know nothing about it. It's an MVP, and I have a laundry list of enhancements/feature requests/things I want to do. Still, any non-obvious feedback is welcome. https://cointipping.com

Show HN: I crafted the simplest way to Gift Bitcoin this Christmas The link is: www.spreadthecoin.com For the past two weeks, I have been building a Bitcoin Christmas(/Happy Holidays) Card company --> and it has just launched (today) at www.spreadthecoin.com . The "Certificate" makes it easy for Bitcoiners to give their friends and family their first Bitcoin (with suggestions on how to spend/use it)! It is meant to play-well with home-printers and can suffice as a last-minute gift idea. I think that Christmas morning/Hanukkah is an excellent opportunity to gift coins to…

Hi HN! For the last few weeks I've been building an algotrading bot based on the Supertrend indicator. It's a trend-following bot that uses the Supertrend lines as support/resistances to enter long/short trades and it's currently running in simulated mode (not real money) on all Binance futures pairs. I've written a somewhat detailed write-up about the strategy here: https://ailef.tech/2021/05/20/im-building-a-cryptocurrency-trading-bot-that-you-can-follow-live-on-telegram/ The cool thing about the bot is that he reports everything on his Telegram…

Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last 3 startups failed, and a common challenge in all of them was figuring out how to reach my audience. Recently I started with cold outreach (its a struggle, since I dont have much experience with marketing). I am finding leads mainly using exa.ai websets (web vector search, extremelly good for multiple use cases, recommend checking them out) and then sending them through smartlead. I ran the campaign for the past 30 days and 12-15% emails always bounced. This wasted my email credits & chances of reaching…
